Subject: Add DT support for fixed PHYs Hello, Here is a fourth version of the patch set that adds a Device Tree binding and the related code to support fixed PHYs. I'm hoping to get this merged in 3.16. Changes since v3: * Rebased on top of v3.15-rc5 * In patch "net: phy: decouple PHY id and PHY address in fixed PHY driver", changed the PHY ID of fixed PHYs from 0xdeadbeef to 0x0, as suggested by Grant Likely. * Fixed the !CONFIG_PHY_FIXED case in patch "net: phy: extend fixed driver with fixed_phy_register()". Noticed by Florian Fainelli. * Added Acked-by from Grant Likely and Florian Fainelli on patch "net: phy: extend fixed driver with fixed_phy_register()". * Reworked the new fixed-link DT binding to be just a sub-node of the Ethernet MAC node, and not a node referenced by the 'phy' property. This was requested by Grant Likely. * Reworked the code implementing the new DT binding to also make it accept the old, single property based, DT binding. * Added a patch that actually uses the new fixed link DT binding for the Armada XP Matrix board. Changes since v2: * Rebased on top of v3.14-rc1, and re-tested on hardware. * Removed the RFC tag, since there seems to be some real interest in this feature, and the code has gone through several iterations already. * The error handling in fixed_phy_register() has been fixed. Changes since v1: * Instead of using a 'fixed-link' property inside the Ethernet device DT node, with a fairly cryptic succession of integer values, we now use a PHY subnode under the Ethernet device DT node, with explicit properties to configure the duplex, speed, pause and other PHY properties. * The PHY address is automatically allocated by the kernel and no longer visible in the Device Tree binding. * The PHY device is created directly when the network driver calls of_phy_connect_fixed_link(), and associated to the PHY DT node, which allows the existing of_phy_connect() function to work, without the need to use the deprecated of_phy_connect_fixed_link().
